Stanislas d8aa625639 feat: add native firewalld support (#1388) ...

## Summary

- Add native firewalld support for RHEL/Fedora/CentOS systems
- When firewalld is active, use `firewall-cmd --permanent` instead of
raw iptables
- Rules persist across `firewall-cmd --reload`
- Fall back to iptables when firewalld is not active
- Add `After=firewalld.service` to iptables systemd unit for safety

## Changes

**Install:** Detect firewalld, use `firewall-cmd` to add port,
masquerade, and rich rules. Fall back to iptables if inactive.

**Uninstall:** Detect which method was used and clean up accordingly.

**Tests:** Add `fedora-42-firewalld` CI test with firewalld enabled.
